Western Digital has developed flash-enhanced drives with OptiNAND technology by vertically integrating their NAND flash with their HDDs. Western Digital HDDs have been leaders in areal density with technologies of energy-assisted magnetic recording technology (EAMR), triple-stage actuator (TSA), HelioSeal, and now OptiNAND technology. Higher areal density means higher capacities to meet storage challenges.
The Ultrastar DC HC560, with the first implementation of OptiNAND technology's capacity-enabling features, delivers a 20TB capacity in a nine-disk platform (2.2TB/platter) with the CMR recording format.
